Given numbers are 426,646,983,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,646,983,284 is 270517668.
Find LCM of 426,646,983,284 with Prime Factorization
2 | 426, 646, 983, 284 |
71 | 213, 323, 983, 142 |
3, 323, 983, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 3 x 323 x 983 x 2 = 270517668
Therefore, the lowest common multiple of 426,646,983,284 is 270517668.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
426 x 646 x 983 x 284 = 76827017712
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
426 : 1, 2, 3, 6, 71, 142, 213, 426
646 : 1, 2, 17, 19, 34, 38, 323, 646
983 : 1, 983
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,646,983,284, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
646:2x 17x 19
983:983
284:2x 2x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 71 = 284
Therefore, the value for common factors is 284.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 76827017712/(1x284)
LCM = 76827017712/284
LCM = 270517668
Thus, we can understand that the LCM of 426,646,983,284 is 270517668.
